Application filed November 16, 1912, Serial No. 731,309.

To all whom it may concern:

Be it known that l, ROBERT A. SCHULZTY, a citizen of the United States, residing at Maple Grove, in the county lilenitowoe and State of YVisconsin, have invented a new and useful illilk-iigitator, of Wi'llCll the following is a specification.

My invention relates to a device or stirring mill: in the process oi the 4 and consists of mechanism for per. by mechanical means W. has for a a time usually been done W1 11 tool in the hands of the cheese inelre 7 and its objectis, to lessen the manual labor iii cheese melting and at the same time leave the mill; in e. ter condition than it would be were the stirringof the mill; performed with :1 t in the hands of th cheese maker the mechanism for it consisting of svJingin which is suspended from the over head work of the room in which the Work is be. ried on and dropped down into the nnllt in a mill; vet the swinging ironic being; given motion transversely of the mill; vet by means of a crank upon shaft that crrsnged for revolution and is provided with a connecting ed in engagement with swinging frame, the part of th that extends into the rat consist made to be swung upward out of he milk and the entire ironic swung}; npwerd t Ward the ceiling and out of the Way of the workmen around the vet, Where may be secured in any suitable manner.

The mechanism is shown in the LlCCGDlpanying dranving in which Figure 1 is a longitudinal elevation of the agitator fram and a she-l t by WfllCll it is operated, With a mill: vat in vertical sect'on under the same. 2 is a vertical section of the milk vet transversely thereof and of the swinging frame to the l the line a, a, 0i 1, its shaft and op ra ing mechanism being in elevation. is a, plan of a stiffener bar that is c to the three swinging bars ll'lll-l carry agitator rake heed. Fig. 4 is a side elevetion of a clamp bolt by which said stiitl'ener bar is connected to the vertical swinging: bars. Fig. 5 is a vertical section and plan respectively of a rectangular clenip securing the rake head to the suspension bars.

Fig. 6 is a side elevation of e bracket to he bolted to the over head work of a room from which the suspension bars are to be Specification of Letters Patent.

is at face view and 7, are

1, indicates the ceiling :1 part of the over head work oi room the mill; agitator end its operating}; incchunis are secured; brackets, ol which three will ordinnrily he sutlieient. that are secured to the over head Work with bolts :1, iron; which ligl'it bars of wood are suspenoeo pivot bolts therein. and can he re thereon with pins 6. or other convenie l vice. These bars are rectangular in section, and extend downward to distance above the mill; 2'". intermediate their ends a. stiilcner bar 8. is secured to each bar 5 with clamps (shown in elevation in Fig. 4-,) said chimps inclosing both the bars and bar 8, so that they are not weakened by loring' holes through them. l rein the lower ends 01" the bars an inerted rake head 10, SllS 'lClHltzil, the rake heed having handles 11, spaced to correspond with the position of the bnrs 5. d pivoted about niid ray their length to the lower ends of said bars upon bolts i l socket 13, formed of bond metal is pro ided upon each bar 5 which fitted to sli le longitudinally thereon and slip over the upper end of the *elte handle which is pivoted to it. lt nild be noted that tlie upper end of each handle is made nperi for fitting the bevel of the socket. as they are shown in F' 5 to be orovioed with bevel at one end so that the sockets will naturally Work downward in the operation of the agitator and remain tightly around the bars a rake handles. The rake heard is providtsil with e. series of teeth 1%, Wlich extend upvrzird therefrom and eilectually stir the milk as the rake head is swung lock and forth in the mil; which niny be in the vet.

The central suspension bar is provided with a metallic sleeve 15. which may be se- P- d thereto in any suitable manner. but

.el adjustment thereon, is it suits ole manner n illCll it can be SCSHL,

above described long i th swi of movement end can be re :ee to gust stril' ties of th inilk I) 5 L Jet upon each side oi the vet ill. eecii oscillation of the rake head. it a suitable distance from the suspended bars a shaft 17, is journaled for revolution in journal boxes 18, mounted in hangers 19, which are suspended from the over head work and secured thereto with bolts 3. Tight and loose pulleys :20 and 90, are mounted upon said shaft, the tight pulley having the belt 21 shifted to it the shaft can be revolved rem any available source of power. A crank wheel 22, is mounted upon one end of the shaft and a crank pin 23, is held in a slot from which a connecting rod 25 extends to the pin 26, which extends outward from the sleeve 15. By means of the slotin the crank wheel the extent of the winging movement of the rake head can be regulated the same as by moving the sleeve 15.

By swinging the frame and rake head to one side of the vat and slipping the sock ts 13 off of the handles ll, the rake head can be swung into the position of it in broken lines in Fig. 2, and then by disconnecting the rod 25, the entire frame can be swung upward, as is shown by the end of the bar 5 shown in broken lines at the upper left hand corner in Fig. 2, and be secured in any con venient manner, out of the way of the workmen while doing other work around the vat. In using the agitator it is intended to swing the rake head the full width of the vat and contact with its sides slightly, so that therev is momentany rest in its movement which allows the milk to partially settle in readiness for th return movement of the rake, and thereby mix the milk in a thorough manne;

Having described my invention, what I claim and desire to secure by Letters Patent, is,

1. A milk agitator, consisting of a vat for holding milk, a frame suspended for oscillation vertically over the longitudinal center of said vat and consisting of a plurality of bars suspended, each from a pivotal bracket secured to the over head work of a room. said bars extending downward to a point above the milk vat, a wrist pin upon one of said bars, a milk stirrer consisting of a rake head arranged near the bottom of the milk vat and a series of teeth spaced apart thereon, handles to the rake head corresponding; in position ther on with the position of said oscillating bars pivoted intermediate their ends to the lower ends of said bars, and adapted to be swung at an angle therewith, means for holding said handles parallel with said bars. a shaft mounted for revolution in a suitable position relative to sail frame, a crank upon said shaft, a wrist pin upon said crank and a rod connecting said wrist pin and the wrist pin upon one of said bars aforesaid.

2. A milk agitator consisting of a vat for holding milk, a frame suspended for oscillation, vertically over the longitudinal center of said vat and consisting of a plurality of bars of wood suspended, each from a pivotal element secured to the over head work of a room and extending downward to a pointabove the vat, a horizontally arranged stiffener bar of wood connecting with each of said bars intermediate their ends and spacing them ap. rt a rake head formed of wood, a series of teeth spaced a short distance apart extending upwarl from the rake head, handles of wood corresponding with the number and position of said suspended bars pivotally attached intermediate their ends to the lower ends of said bars, a socket mounted to slide upon each vertically suspended bar and inclose the outer end of a handle and clamp it alongside of one of said bars, and cans for swinging said frame and rake head transversely of the milk vat.

3. in a milk agitator, a milk stirring device consisting of a frame formed of a plurality of bars of wood, each arranged to be suspended for oscillation from a pivotal element secured to the over head work of a room, a stiffener bar formed of wood arranged horizontally and connected to each suspended bar with a clamp bolt inclosing both vertical and horizontal bars, a rake head formed of wood, a series of teeth extending upward from th rake head and spaced a short distance apart thereon, handles corresponding in number and position with the number and position of said suspended bars extending upward from the rake head and pivoted intermediate their ends to the lower ends of their respective suspension bars, and a metallic rectangular socket for each handle slidably arranged upon each suspension bar, one end of which sockets is angularlv disposed relative to the other end and is adapted to fit at said angular disposed end the tapering end of a handle and thereby have a tendency to become tightened thereon when in use.

a. In a milk agitator for a milk vat, a milk stirring device consisting of a rake head arranged for a swinging movement transversely of the milk vat, a series of rake teeth spaced a short distance apart and extending upward from said rake head and a plurality of handles by which the rake head can be swung.
